` JAMEsw. TODD, or NEw ROCHELLE, NEW YoEK.

SASH-FASTENER.

SPECIFICATION forming part of Letters Patent No. 225,541, dated March 16, 1880.

Application led February 9, 1880.

To all 'whom it ma/y concern:

Be it known that I, JAMESW. TODD, of New Rochelle, in the county of Westchester and State of New York, have invented an Improvement in Sash-Fastenings, of which the followhave been made to hold a sash-lock that turns horizontally upon a vertical pivot.

Myinvention consists in the combination, in a sash-fastening, of a spring-catch upon the top of the lower sash, a frame fastened to the upper sash, a swinging segment pivoted to such frame, and a stop to regulate the extent of movement of the said swinging segment, so that its lowerend will be caught and iirmly held by the spring-catch.

This sash-fastening is very solid and durable in its construction, and any eort to pry open the window causes the parts of the lock to hold upon each other` with increased firmness.

In the drawings, Figure 1 is a plan of the sash-lock, and Fig. 2 is a vertical central section at the line a' and Fig. 3 is a cross-section atthe line y y.

The frame-is made with a bottom plate, a, that is fastened securely upon the meeting-rail b of the top sash, and the vertical side pieces, c c, of the frame receive between them the wedgeshaped segment d, through which and the side pieces, c c, the pivot-pin c passes, so that the segment is free to swing on said pivot e.

' The lower end of the segment is curved and notched transversely across its face, and the upper end of the segment extends above the pivot, so that it may be used in swinging the segment in either direction, and when the lock is to be fastened the lower end'of the segment dis swung over the top rail, f, ofthe lower sash and passes above the plate h, upon which are the curved bearing-Han ges Z Jfor the end of the segment to rest upon, and between these bearing-flanges there is a latch, t', upon the pivot o, having a spring, r, beneath its outer end. This latch catches into the notch on the lower end of the swinging segment and holds the same firmly in place to lock the sash.

In the side of the swinging segment there is a recessed panel or slot, into which the end of the screw-stop s passes, such screw being in one of the verticalparts of the frame, so as to limit the swinging movement of the pivoted segment in both directions; or said vpivoted segment may be made with a slot through its lower portion, through which and the side frames a rod passes and limits the movement of said segment; and I also provide a spring, t, let into or attached to the side of the segment. Said spring, bearing against the inside of the vertical fra-me, acts by friction to hold the segment in any position it may be placed in.

I claim as my inventionl. The combination, in a sash-lock, of the frame a c, segment d, pivoted at e and recessed for the stop s, and the plate h, bearingilanges l, and spring-catch i, substantially as set forth.

2. The combination, with the pivoted segment d, ofthe frictional spring t, stop s, frame a c, and catch z', substantially as specified.

Signed by me this 6th day of February, A. D. 1880.

JAMES W. TODD.
